Possible problems: 1, plus some price difference, plus commission or handling fee.

2. There may be gambling.

3. When the market changes greatly, the data update of the small platform can't keep up, which affects the price at the time of trading.

4. The settlement company that chooses this trading platform may not be a regular company. Just look it up on the official website of NFA (American Futures Association). Regular account opening companies and clearing companies are supervised by NFA and CFTC, such as Global Futures, FX Solutions and FXCM.

I have consulted Huishengmen, the general counsel of Global Futures in China. Global Futures is one of the largest independent brokerage companies in the United States, so Huishengmen's answer about the platform is credible. At present, FX chooses the G.T.S platform, which has a good reputation. FXCM has its own foreign exchange trading station and MT4 platform. I've never tried it.

I suggest you do more research, learn more, and then carefully choose an account opening company. Both the account opening company and the settlement company must accept the supervision of NFA. For example, global futures is an account opening company and should be supervised. FX SOLUTIONS is a clearing company and must be regulated. Only in this way can you consider opening an account.
